Modification of Vitreoretinal Instruments: Perfection or Complication

Advantages: To reduce the disadvantages of standard vitreoretinal instruments (cannulas and ILM forceps) which arise during the use on eyes with long axial length. Methods: Two types of aspiration cannulas and one ILM forceps for surgery on eyes with long axial length were designed on schematic eye drawing and manufactured. Forty-four eyes with high-grade myopia (axial length 28-33.5 mm) were operated for retinal detachment and macular...

Modified Vitreo Retinal Instruments for Macular Surgery on Eyes with High Myopia

Advantages: To improve certain vitreo-retinal instruments to enhance the accesses to posterior pole and avoid complications during macular surgery in highly myopic eyes. Methods: Modified double bent aspiration 23-gauge cannula with 30.00 mm working part was used during pars plana vitrectomy in highly myopic eyes. The aspiration of residual PFCL or BSS with modified cannula was performed under visual control using different kinds of...
